Ore grades during the third quarter were similar to the second quarter and approximately 9% lower than the same period a year ago. The lower grade is due to initiation of mine development in the lowest levels of the mine, locally increased dilution in long-hole stopes higher in the mine, and an overall increased supply of economic ore from outside the currently-defined mine plan resource boundary. In the fourth quarter, grades are expected to increase as the mine sequences back into increased ore feed from the 99 zone where grades exceed 900 grams per tonne of silver. With mill throughput improving and an anticipation of improving grades, Alexco expects silver production to increase again during the fourth quarter. In addition, Alexco is in the process of recalculating the overall Bellekeno resource. Results are anticipated by the end of the year, with an expectation of extending the life of the Bellekeno mine.

At Alexco's Lucky Queen and Onek mines, development work is progressing as planned in preparation for production, which is anticipated to begin concurrently with receipt of appropriate regulatory authorizations, likely later in the fourth quarter or in the first quarter of 2013.

Alexco President and Chief Executive Officer Clynt Nauman said, "We have made some important improvements in mill efficiency this quarter, both in throughput and silver-lead recoveries. We intend to continue to build on this improvement toward our 400 tpd throughput target in the mill, especially with the expectation of feed from two new mines coming on stream in 2013. After nine quarters of production from the Bellekeno mine since commissioning, we will likely reach a point during the fourth quarter where mill throughput will outpace Bellekeno mine output capacity. While our focus in the fourth quarter will remain on continually improving mill operations, it is anticipated that with the Bellekeno mine operating at capacity and with newly available and improving capacity in the mill, there will be increased opportunity to catch up on deferred mill maintenance, crew training and preparation for sustained winter operations. All of this will pay additional benefits when our new Lucky Queen and Onek mines come on stream."

Nauman also added, "Our exploration efforts at Keno Hill have been extremely successful this year. Recent results from the Flame & Moth discovery adjacent to the mill are particularly exciting as we continue to expand this significant discovery and move towards an updated resource in the first quarter of 2013. We anticipate following up this work with engineering, extensive trade-off studies and permitting-related activities in the latter half of 2013."

About Alexco

Alexco Resource Corp. owns and operates the Bellekeno silver mine, one of several mineral properties held by Alexco which encompass substantially all of the historical Keno Hill Silver District located in Canada's Yukon Territory. Bellekeno, which commenced commercial production at the beginning of calendar year 2011, is Canada's only operating primary silver mine. Alexco's primary near-term exploration objective is to unlock value in the silver-rich Keno Hill District, and is focused on growth by advancing its promising District properties to development decisions. The Company's goal is to produce 7 million to 10 million ounces of silver annually within the next decade. Employing a unique business model, Alexco also provides mine-related environmental services, remediation technologies and reclamation and mine closure services to both government and industry clients through the Alexco Environmental Group, its wholly-owned environmental services division.

Keno Hill Silver District History

Between 1921 and 1988, the Keno Hill Silver District was a world-class silver producer, with more than 217 million ounces of silver produced at average grades of 40.5 ounces per ton silver, 5.6% lead and 3.1% zinc (Yukon Government's Minfile database). These historical production grades would rank Keno Hill in the top 3% by grade of today's global silver producers.
